FASTENING- FOR CAR-DOORS.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application led January 23, 1908. Serial No. 412,278.

To all whom 'it may concern.'

Beit known that I, ALBERT C. ScnRoEDER, citizen of the United States, residing at Pomeroy, in the county of Calhoun and State of Iowa, have invented certain new and useful Improvements in F astenings for Car- Doors, of which the following is a specification.

This invention comprehends certain new and useful improvements in doors and locking means therefor, and the invention has for its object a simple, durable and eflicient construction of door for use on railway cars, storage bins, in warehouses or elevators, or for any receptacle generally for grain, coal, or other commodities, the purpose being to provide a door which will be easy to manipulate, secure when locked in closed position and of light and strong construction, which will produce a sufficiently tight joint when closed.

Vith these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and then point out the novel features in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is 'a perspective view of a door constructed in accordance with my invention Fig. 2 is a horizontal sectional view thereof; Fig. 3 is a rear elevation, with the doors open; Fig. 4 is a detail sectional view of the lock casing; and, Fig. 5 is a similar view illustrating the means for working the locking slide.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates a railroad car with which my invention is embodied, which is selected for the purpose of illustration only, as it is to be understood that my improved door is applicable for use in a doorway of any receptacle, as above noted.

2designates the vertical doorway timbers or jambs, and 3 the sill timber which is preferably covered by a metallic sheet 4 secured thereto in any desired way.

5 and- 6 designate the two doors which are arranged to swing in opposite directions about vertical axes.

Each of the doors is preferably composed of metal, although other material may be used, and is preferably provided with battens 7 formed of channel material, as clearly illustrated in the drawings. At one edge each door is provided with a series of spaced knuckles S arranged to fit'between a series of corresponding knuckles 9 that are formed on an intermediate hinge plate 10, the knuckles 9 being set back from one edge of said intermediate hinge plate, to define an overlap 11 so as to effect a tight joint between the doors and the said hinge plates and revent leakage. In addition to the set-baclk knuckles 9, each of the intermediate hinge plates 10 is provided with a series ofoppositely facing hinge knuckles 13 alternating with knuckles 14 formed on a stationary hinge plate 15. The two stationary hinge plates 15 are secured in any desired way to the rear face of the vertical doorway timbers or jambs 2. By this means a two-way hinge is provided for each of the doors so that they may be swung forwardly through the doorway or turned backwardly to lie against the inner wall of the car or other receptacle provided with the improvements.

One of the doors is provided with a series of superposed and transversely extending latch bars.. Each of these latch bars comprises hinge sections 16 and 17 which, in the present instance are formed of channel metal connected together by an abutting joint, so as to limit the hinged movement in one direction when the sections 17 are extended out in straight relation to the attached sections 16. The free or swinging sections 17 of the latch bars are designed to project across the other door, as clearly illustrated in the drawings and to` be engaged with a casing 18 which is secured to and extends vertically along one of the door jambs 2, being attached to the inner and front faces thereof, as shown. The casing 18 is provided with several slots 19 for the reception of the free ends of the respective swinging sections 17 of the latch bars, and to secure the said sections locked within the casing, I provide an angular vertically movable locking slide 2() which is mounted within the casing-18, one angularly disposed member of said locking slide being provided with a series of edge notches 21 designed, when the slide is moved in one direction to register with the respective slots 19 and to move out of registry with said slots when the slide is moved in the opposite direction. In the present arrangement of parts, it will be seen that after the swinging section 17 of the latch bars have been passed through slots 19 and past the notches 21, the locking slide 20 may be moved downwardly within the casing 18 so as to carry the notches out of registry with the slots and present a solid portion of the locking slide in front of the ends of the latch bars so as to securely lock the same in place. In order to provide for a sufficiently easy movement of the locking slide 20, antifriction rollers 22 are mounted within the casing 18 and bear against said slide as shown. To effect the u ward and downward movements of the loc ring slide, the same is provided with a slot 23 and the casing is formed with an opening 24 through which a pin or bar 25 may be inserted and entered in the slot 23 so that by bearing down upon the outer end of the pin or bar 25, the slide may be raised, and by pulling upwardly upon the outer end of said bar, the slide may be lowered.

26 designates hinge fasteners in the nature of turn-buttons that may be secured to the inner walls of the car or other receptacle so as to hold the doors in open position when they are swung inwardly. By constructing the latch bars in hinge sections, as before described, the swinging ends thereof may be turned out of the way of the terminal elevators and coal docks, so as not to interfere with the ready unloading of the car.

From the foregoing description in connection with the accompanying drawings, it will be seen that I have provided a very simple,

' durable and efficient construction of door 1. The combination with a car or other receptacle provided with a doorway, of doors hinged to the opposite sides of said doorway, latch bars constructed in hinged sections of which one is secured to one of said doors, and of which the other is adapted to project over the other door across the doorway, a casing secured to one side of the doorway and formed with slots adapted to receive the free ends of said latch bars, and a locking slide mounted to move in said casing, and formed with notches designed to register with the slots in the casing whereby the free ends of the latch bars may be passed into said slots and past the notches, the slide being adapted to be moved so as to carry the notches out of registry with the slots to lock the latch bars therein.

2. The combination with a car or other receptacle provided with a doorway, of a door hinged in the doorway, a transversely eX- tending'latch bar secured to said door, a casing secured to the doorway and formed with a slot adapted to receive the free end of the latch bar, a vertically movable slide mounted in said casing and formed in one edge with a notch adapted to register with the slot, whereby the free edge of the latch bar may be entered into the slot and carried past the notch, the slide being arranged to be moved so as to carry its notch out of registry with the slot and lock the latch bar in the casing.

3. The combination with a car or other receptacle provided with a doorway, of a door hinged to one side of said doorway, a transversely extending latch bar secured to said door, a casing secured to the/'other side of the doorway and formed with a slot, a vertically disposed slide mounted in said casing and formed in one edge with a notch adapted to register with the slot, whereby thefree ends of the latch bar maybe entered in the slot and carried past the notch, the slide being provided with a slot and the casing being formed with an opening -in registry with said slot, whereby a bar may be entered through the opening and inserted in said slot to raise and lower the slide.

In testimony whereof I aflix my signature in presence of two witnesses.
